Domain Mapping issue - "Domain unavailable to access"

I bought a domain 2 days ago, mapped the domain over 24 hours ago, added the domain to the Wpengine domains section, but the Domain mapping won't work. See screenshot.

This is installed on multisite, right now, when I put in my custom domain, it goes to the main domain. So, I know the DNS is pointed correctly.

I made sure to give you guys access to the site's back end in case you need to get in and look around.
